Ajax captain Jan Vertonghen due for medical at Tottenham

Tottenham Hotspur are set to complete the signing of the Ajax captain, Jan Vertonghen, after the club announced they had agreed terms yesterday.

Spurs have been tracking the Belgium defender since last season as he helped Ajax win their second consecutive Eredivisie title. Vertonghen is due to undergo a medical at White Hart Lane this week before completing a deal.

"We are delighted to announce that we have reached agreement with Ajax for the transfer of Jan Vertonghen, subject to a medical," a club statement read. "The 2011-12 campaign was the Belgium international's most successful season – being named Ajax captain at the start and going on to lead the Dutch side to their second straight league title. In total, Jan made 220 appearances and scored 28 goals for Ajax since making his debut for them in 2006."

Vertonghen said: "I'm 25 and I feel ready to play in the Premier League. I think I'm ready for the club."

The Belgian will bolster a Spurs central defence that has been weakened by the departure of Ryan Nelsen and the likely retirement of the long-serving club captain, Ledley King.

Vertonghen is the second signing since the former Chelsea manager Andre Villas-Boas took over at Spurs this month, after the Icelandic midfielder Gylfi Sigurdsson, who impressed at Swansea last season while on loan from Hamburg, agreed a move last week.
